The invention relates to a method for combining the different minerals used for the jewels comprising the process steps of thinning and fixing to each other the bottom and the top layers (1, 3), thinning by means of extruding from the cylinder the structure (A) that forms as a result of fixing the bottom and the top layers (1, 3), preparing the mixture comprising the welding material in the form of a plate and thus forming the intermediate layer (2), placing the intermediate layer (2) comprising the welding material between the two layers (1, 3) and injecting an oxygen-repelling gas, in order to obtain a fixed structure (A) by means of kiln-drying process carried out for a certain time at a particular temperature, obtaining the thin structure (B) by thinning the obtained fixed structure (A) by means of extruding it from the cylinder.
